FOLDING CHAIR.

SpeCifiCafiOn of Letters Patent. Patented Nov. 30, 1915,

Application filed December 11, 1913. Serial No. 806,039.

To all whom it may concern.

Be it known that I, OLIVER P. ROBINSON, a citizen of the United States, residing at -Blackburn, in the county of Pawnee and State of Oklahoma, have invented certain new and useful Improvements in Folding Chairs, of which the following is a specification.

This invention relates to an improved folding chair, and the principal object of the invention is to provide a chair which is so constructed that the back and legs may connect the back, arms, and legs that the chair may be folded into a very compact mass.

This invention is illustrated in the accompanying drawings wherein Figure 1 is a rear elevation of the im-- proved chair; Fig. 2 is a bottom plan view of the improved chair; Fig. 3 is a vertical sectional view through the improved chair; Fig. 1 is an enlarged fragmentary view showing the manner of connecting one of the arms with the back; Fig. 5 is afragmentary' view showing the manner of connecting the front braces for the legs with the seat of the chair; Fig. 6 is a fragmentary elevation of one of the rear braces, the other brace being shown in section.

The seat 10 of this chair is secured to the front and rear cross strips 11 and 12 which are secured to the side strips 13. The front and rear legs 14 and 15 which carry the rockers 15 are connected with the strips 13 by means of the pivot brackets 16 so that the legs of the chair may be folded to lie flat against the seat of the chair. The forward braces 17 are pivotally connected with the forward cross strip 11 by means of the pivot bracket 18 and have their lower end portions removably connected with the rockers by means of the plates 19. The rear braces 20 and 21 are pivotally connected with the side strips 13 by means of the plates 22 and are removably connected with the rockers by means of the plates 23. These braces20 and'21 pass each other diagonally as shown in Fig. 1 and are interlocked as shown in Fig. 6. From inspection of Fig. 1, it will'be readily seen that the folding legs will be very securely held in a set-up position and all danger of the legs collapsing or breaking done away with.

The back which is indicated in general by the numeral 2& comprisesthe side bars 25 which are connected at their upper ends by the cross bar 26 and braced by the diagonal braces 27. .These side bars 25 are pivotally'connected with the seat 10 by means of the U-shaped pivot brackets 28 so that the back may be folded down upon the arms .29 which are pivotally connected with the seat bymeans ofthe pivot brackets 30. A

triangularly-shaped plate 31 is pivotally mounted in a slot 32in each of the arms 29,

and these plates are provided with openings 33 through which a securing rod 34;

slidably mounted'on the braces 27, is intended to pass. The plates 31 extend beyond the slots 35 formed in the side bars 25, and it will thus be seen that when the rod 3st has been passed through a selected set of openings 33, the arms will be removably connected with the back and the back thus held in a raised position.

It should be noted that when the chair is in the set-up position shown in Figs. 1 and 3 the braces 27 will engage the seat of the chair as clearly shown in Fig. 1 and thus serve as means for limiting the pivotal move ment of the chair back in one direction.

When this chair is in use, it is in the position shown in Figs. 1 and 3. If it is desired to fold the chair, the rod 34 isfirst moved to release the arms which are first folded upon the chair seat 10 and the back 24 is then folded upon the arms. The chair can then be turned to the position shown in Fig. 2 and the braces 17 20, and 21 released from the rockers. These braces are turned to the position indicated in dotted lines in It should be 'particularl' noted that the arms of the pivotbrackets l6 and 28 are of such length that the back may be folded fiat upon the folded arms and the legs folded 7 upon the braces. It should also be noted that the plates 3l are so constructed that the incline of the back may be regulated accord ing to the desires of the person using the I chair by inserting the rod 34: through the proper set of openings 33.

What is claimed is:'

1. A chair comprising a seat, arms pivotally connected With said seat, a back pivotally connected with said seat and provided With slots positioned in alinement Withsaid arms When said arms and back are raised, plates pivotally connected With said arms and extending through the slots of said back,

said plates being provided With openings,

and a transversely extending rod slidably connected With said back and extending through the openings of said plates to re movably connect said arms With said back and hold said arms and back in a raised poa raised position, said back being held at a selected angle.

3. A chair comprising a seat, arms pivotally connected With said seat, a back pivotally connected with said seat, plates pivotally connected with said arms and provided With a plurality of openings, bracing bars for said back, and a rod slidably carried by said bracing bars and passing through a selected set of the openings in said plates to removably connect said arms With said back and releasably hold said back at an adjusted angle.

4. A chair comprising a seat, arms carried by said seat, a back pivotally connected With said seat, bracing bars for said back constituting means for limiting the pivotal movement of the back in one direction, said back being provided With slots and said bracing bars being provided With alined openings, plates pivotally connected With said arms and passing through the slots of said back and provided With openings, and a securing rod slidably mounted in the openings of said bracing bars and passing through the openings of said plates to releasably hold said,

back inan adjusted position.
